Product Description
The TVS-TPO series (2+1) X1 combiner (2+1) X1 Pump+Signal Combiner) is used to combine two multimode pump lasers and one single-mode signal light into a double clad fiber, achieving the goal of signal light being amplified by the pump light. It has the characteristics of high power resistance, high signal transmission efficiency, high pump coupling efficiency, wavelength insensitivity, and high stability and reliability in biaxial operation. It is mainly used in polarization maintaining fiber lasers, polarization maintaining amplifiers, polarization maintaining sensing systems, and scientific research applications.
